Description

The TPS3850 combines a precision voltage supervisor with a programmable window watchdog timer. The TPS3850 window comparator achieves 0.8% accuracy (–40°C to +125°C) for both overvoltage (VIT+(OV)) and undervoltage (VIT–(UV)) thresholds on the SENSE pin. The TPS3850 also includes accurate hysteresis on both thresholds, making the device ideal for use with tight tolerance systems. The supervisorRESETdelay can be set by factory-programmed default delay settings, or programmed by an external capacitor. The factory-programmedRESETdelay features a 9.5% accuracy, high-precision delay timing. The TPS3850 includes a programmable window watchdog timer for a wide variety of applications. The dedicated watchdog output (WDO) enables increased resolution to help determine the nature of fault conditions. The window watchdog timeouts can be set by factory-programmed default delay settings, or programmed by an external capacitor. The watchdog can be disabled via logic pins to avoid undesired watchdog timeouts during the development process. The TPS3850 is available in a small 3.00-mm × 3.00-mm, 10-pin VSON package.
